to adjust the mounting block:
1. disConneCt saW FroM poWer!
2. raise the blade all the way up, move the
sliding table to the side, and open the lower
blade cover to gain access to the mounting
block.
3. loosen the lock nut that secures the spread-
er/riving knife to the mounting block, and
remove the spreader/riving knife.
4. adjust the each pair of set screws that
controls the direction required to move the
mounting block so the spreader/riving knife
can be aligned with the blade. Make sure to
move both set screws in even increments.
5. reinstall the spreader/riving knife and check
the alignment with the blade. repeat step 4
as necessary until the spreader/riving knife is
properly aligned to the blade.
note: If you discover that the spreader/riving
knife is bent and cannot be properly aligned
with the blade, it is possible to bend it into
alignment, but make sure that the final result
is precisely aligned so the risk of kickback is
not increased. If the spreader/riving knife is
bent, and you cannot easily bend it back into
alignment, we recommend replacing it with a
new one.
6. properly re-install the spreader/riving knife as
described on page 40, close the blade cover,
and move the sliding table back to the center
position.
adjusting mounting
block
the spreader/riving knife must be aligned with the
blade when installed. if the spreader/riving knife
is not aligned with the blade, then the workpiece
will be forced sideways during the cut, which will
increase the risk of kickback.
the spreader/riving knife mounts to a block that
can be repositioned to correctly align the spread-
er/riving knife to the blade.
the mounting block adjusts by turning the set
screws in each corner of the block.

adjusting the mounting block, because it requires
trial-and-error to perform with accuracy.
